Question

This can be a handy functionality to have in a program that works with files/folders. It’s easy enough to actually open the containing folder using:

System.Diagnostics.Process.Start( *path to folder* );

…but how do I go about actually selecting the target file within that parent folder? If I use the Process.Start method it actually attempts to open the file.

According to Windows Explorer Command-Line Options you just need to start an explorer process with /select parameter.

For instance, ‘explorer /select,c:\Windows‘ will open a window with c:\windows folder selected.

So simply Process.Start("explorer.exe", "/select," + filename) should be enough.
